What are the maintenance items for 10,000 kilometers?

Maintenance items for 10,000 kilometers include: 1. Replacement of engine oil and oil filter; 2. Check whether the oil filter element, air filter element, fuel filter element, air conditioning filter element, and transmission oil filter element need to be replaced; 3. Top up windshield washer fluid, antifreeze, and air conditioning refrigerant if insufficient; 4. Check the drive belt for wear; 5. Clean the throttle valve and carbon deposits in the cylinders; 6. Inspect the chassis for damage; 7. Check the body and tires. The benefits of car maintenance: 1. Ensure the vehicle's excellent performance condition; 2. Improve driving safety; 3. Reduce engine noise; 4. Extend the vehicle's service life.

How to Change Engine Oil by Yourself?

The method for changing engine oil independently is: 1. Start the car engine and turn it off when the water temperature reaches the normal range; 2. Use a jack or car lift to raise the vehicle, open the oil drain plug at the bottom, and use a specialized wrench to remove the oil filter; 3. After all the oil has drained, install the new filter with the wrench and pour the specified grade of engine oil into the oil pan. Engine oil, also known as motor lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and dampen vibrations in the engine. It is often referred to as the 'lifeblood' of a car and consists of base oil and additives.

Should a cracked front bumper be repaired?

The cracked front bumper should be repaired. The front bumper is made of plastic, known as a plastic bumper. Its outer panel and cushioning material are made of plastic, while the crossbeam is formed from cold-rolled sheet metal approximately 1.5mm thick, pressed into a U-shaped channel. The outer panel and cushioning material are attached to the crossbeam, which is then bolted to the vehicle's frame rails. The plastic used in the bumper consists of polyester and polypropylene materials, manufactured through injection molding. In terms of safety, the plastic bumper provides cushioning during low-speed collisions, protecting both the front and rear of the vehicle, as well as pedestrians in the event of an accident. To minimize injury to occupants during side-impact collisions, many cars are equipped with door bumpers to enhance door impact resistance.

Where is the Buick Excelle fuel filter located?

The Buick Excelle fuel filter is located next to the activated carbon canister of the fuel filter element, near the right rear wheel. It can be seen after lifting the vehicle. The replacement method for the fuel filter is as follows: 1. Release the residual pressure in the fuel system; 2. Remove the grounding wire near the fuel filter element; 3. Place a container under the filter; 4. Pull out the fuel inlet pipe and then remove the adjacent fuel outlet pipe; 5. Remove the old fuel filter element to complete the replacement. Precautions for replacing the fuel filter element include: 1. Ensure the overall sealing of the air filter and cabin air filter; 2. Use the gasoline grade specified by the vehicle manufacturer. The fuel filter, also known as the fuel strainer, functions to remove iron oxide, dust, and solid impurities from the fuel, preventing fuel system blockages, reducing mechanical wear, ensuring stable engine operation, and improving reliability.

What is the reasonable engine RPM for shifting gears?

Common vehicles usually shift gears appropriately at 2000-3000 RPM. It is advisable to shift gears when the engine reaches the following RPM ranges: 1. First gear start: Engine RPM around 1000-1500, vehicle speed at 10 km/h, then shift to second gear. 2. Second gear: Engine RPM around 1500-2000, vehicle speed reaching 30 km/h, then release the throttle and shift to third gear. 3. Third gear: Engine RPM around 1500-2000, vehicle speed reaching 40 km/h, then release the throttle and shift to fourth gear. 4. Fourth gear: Engine RPM around 1500-2000, vehicle speed reaching 50-70 km/h, then release the throttle and shift to fifth gear. 5. Fifth gear: Engine RPM around 1500-3000, vehicle speed reaching 80-120 km/h. If there are additional gears, continue upshifting based on the pattern and actual feel.

What are the effects of excessively high engine oil viscosity on a car?

Effects of high-viscosity engine oil on a car: 1. Reduction in engine effective power: High oil viscosity increases the crankshaft's oil stirring resistance, leading to greater internal power loss in the engine. 2. Difficulty in ignition at low RPM: High oil viscosity requires more torque for crankshaft rotation during cold starts, resulting in lower RPM and difficulty in ignition. 3. Poor filter cleaning performance: High oil viscosity slows down circulation speed, reducing the number of passes through the filter and hindering timely removal of wear debris from friction surfaces. 4. Inferior cooling effect: Poor oil flow and slower circulation decrease the rate of heat removal from friction surfaces, resulting in poorer cooling performance and increased risk of engine overheating. 5. Higher carbon residue: High-viscosity oil tends to have larger carbon residue particles and higher solidification points, which can easily clog oil passages.
